* controller. Unfortunately not all implementations get this right.
|
||||
* In particular some have problems with unaligned accesses to the
|
||||
* virtualized PCI registers. This driver always does full dword
|
||||
* writes to work around the issue. Also, in case of a bad BIOS this
|
||||
* driver can be loaded with the "msr=1" parameter which forces using
|
||||
* the Machine Specific Registers to configure the device.
